FIELD OF THE INVENTION

This disclosure relates to approaches for providing continuousconfiguration deployment.

BACKGROUND

Under conventional approaches, computing systems require routinemaintenance for continued operation. For example, a typical computingsystem may need to install system patches on a weekly basis, and systempatches can be quite large (e.g., hundreds of megabytes or severalgigabytes). Additionally, computing systems are typically required to beoffline during maintenance, so maintenance windows are often limited toa short duration (e.g., 2 hours), which may be insufficient to obtain(e.g., download) and install large system patches. Computing systems mayalso have varying maintenance requirements (e.g., different computingsystems may be running different software versions), which can require auser (e.g., an engineer) to manually configure patches for eachdeployment.

SUMMARY

Various embodiments of the present disclosure may include systems,methods, and non-transitory computer readable media configured tofacilitate providing continuous configuration deployment. Aconfiguration definition object may be obtained over a communicationnetwork from a first datastore. The first datastore may comprise aremote datastore. The configuration definition object may be stored in asecond datastore (e.g., local datastore). A first configuration objectmay be generated based on the configuration definition object and one ormore system characteristics. A service request may be received. Thefirst configuration object may be executed in response to receiving theservice request.

In some embodiments, the configuration definition object may be providedin response to the configuration definition object being committed tothe first datastore.

In some embodiments, the remote datastore may be located at a centralserver or a sub server. In some embodiments, the configurationdefinition object may be obtained in advance of a scheduled maintenance.In some embodiments, the service request may be received subsequent toobtaining the configuration definition object.

In some embodiments, the configuration definition object may supportgeneration of multiple different configuration objects. In someembodiments, the one or more system characteristics may comprise systemversion information.

In some embodiments, the systems, methods, and non-transitory computerreadable media may be configured to receive a configuration request froma remote system. The configuration request may indicate theconfiguration definition object. In response to receiving theconfiguration request, the configuration definition object may beprovided to the remote system. The configuration definition object maybe capable of facilitating a generation of a second configuration objectby the remote system. The second configuration object may be generatedbased on the configuration definition object and one or more secondsystem characteristics. The second configuration object may be differentfrom the first configuration object.

DETAILED DESCRIPTION

A claimed solution rooted in computer technology overcomes problemsspecifically arising in the realm of computer technology. In variousimplementations, a computing system may obtain a configurationdefinition object (e.g., files, scripts, binaries or packages) over acommunication network from a remote datastore (e.g., a centrallymaintained hierarchical data repository, and/or a local cache of aremote system). The configuration definition object may be used togenerate different configuration objects (e.g., particular systempatches). For example, a single configuration definition object may beused to automatically generate different system patches based on theparticular characteristics (e.g., version information) of the differentsystems. The obtained configuration definition object may be stored in asecond datastore (e.g., a local cache). In some embodiments, theconfiguration definition object may be obtained and stored in advance ofa scheduled maintenance, which may reduce the downtime associated withthe scheduled maintenance (e.g., by reducing lengthy downloads). In someembodiments, the configuration definition object may be obtained inresponse to the configuration definition object being committed to theremote datastore, which may help ensure that the systems consistentlyobtain current updates without a user (e.g., administrator) having tomanually request and/or provide updates. A configuration object (e.g., aparticular system patch) may be generated from the configurationdefinition object and one or more system characteristics. A servicerequest (e.g., a system patch request associated with a scheduledmaintenance) may be received, and the configuration object may beexecuted to perform a configuration of a computing system (e.g., withoutrequiring user input).

In some embodiments, the computing system may provide configurationdefinition objects to one or more remote systems. For example, thecomputing system may receive a request from a remote system, anddetermine whether it has an appropriate configuration definition objectsufficient to satisfy the request. If it has the configurationdefinition object, the computing system may provide it to the remotesystem. If the computing systems does not have the appropriateconfiguration definition object, it may forward the request to anotherremote system, which in turn may determine if it has the appropriateconfiguration object. This process may be repeated until the appropriateconfiguration definition object is located and/or the request reaches acentral server (e.g., a server maintaining the remote datastore). Thismay help reduce a load on the central server, and may help ensure theremote systems receive updates even under poor network conditions (e.g.,the central server goes down, and/or the remote system loses networkconnectivity with the central server).

The systems and methods disclosed herein enable provision of continuousconfiguration deployment. A configuration definition object file may beused to generate different configuration objects for different system.The configuration definition object may include hierarchalconfigurations, which may be used to configure different systems. Theconfiguration definition object may be provided by a central server toone or more remote systems in advance of a scheduled maintenance. Byobtaining the configuration definition object from the central server inadvance, the remote system(s) may be able to implement themaintenance/configuration without having an active network connectionwith the central server. By obtaining the configuration definitionobject from the central server in advance, the remote system(s) may beable to implement the maintenance/configuration without spendingtime/network resources downloading the necessary file(s) during themaintenance window. This may reduce the time required for maintenance,and may reduce the amount of time a system must be offline formaintenance. A remote system that needs a configuration definitionobject may request the configuration definition object from anotherremote system (sub server), rather than requesting the configurationdefinition object from the central sever. The provision of theconfiguration definition object may be effectuated by a serverapplication (e.g., Java server application) that sits at differentlayers. Individual remote systems may compile the configurationdefinition object(s) for its own purposes and applying the configurationto itself (and/or its nodes). The configuration definition object(s) maybe compiled based on the context/environment of the system (e.g., aremote system, a node) to which the configuration will be applied. Suchprovision/use of the configuration definition objects may allow anetwork of systems to be centrally defined and de-centrally managed.

FIG. 1 illustrates an example environment 100 for providing continuousconfiguration deployment, in accordance with various embodiments. Theexample environment 100 may include a central server 110, a sub server A120, and a sub server B 130. The central server 110, the sub server A120, and the sub server B 130 may include one or more processors andmemory. The processor(s) may be configured to perform various operationsby interpreting machine-readable instructions stored in the memory. Thecentral server 110 may communicate with the sub server A 120 and/or thesub server B 130 via one or more networks. The environment 100 may alsoinclude one or more datastores (not shown) that is accessible to thecentral server 110 and/or one or more of the sub servers 120, 130 viathe network(s). In some embodiments, the datastore(s) may includevarious databases, application functionalities, application/datapackages, and/or other data that are available for download,installation, and/or execution.

In various embodiments, the central server 110 may include a datastore112, a configuration engine 114, and a communication engine 116. Thedatastore 112 may include structured and/or unstructured sets of datathat can be divided/extracted for provision when needed by a componentof the environment 100 (e.g., the central server 110, the sub server A120, the sub server B 130, nodes of the central server 110/the subservers 120, 130). The datastore 112 may include one or morerepositories (e.g., version control repository, Git repository, and/orthe like) for storing changes for one or more components of theenvironment 100. The datastore 112 may include one or more centrallymaintained hierarchical data repositories. The datastore 112 may includeone or more configuration definition objects, configuration objects,and/or other files to be used by one or more components of theenvironment 100. The datastore 112 may include different data analysismodules that facilitate different data analysis tasks, patches for theapplications/systems, custom application/functionalities built forparticular application/systems, and/or other information to be used inthe environment 100.

A configuration definition object may define one or more configurationsfor one or more systems. Configurations for multiple systems may bedefined by one or more hierarchical configuration files such that eachsystem does not require separate configuration file(s). A configurationdefinition object may include one or more files used to compile and/orotherwise generate one or more configuration objects. A configurationobject may refer to one or more files for configuring a system. Forexample, a configuration definition object may include one or more offiles, scripts, binaries, packages, and/or other files which may be usedto compile one or more configuration objects. For example, aconfiguration object may include one or more patches/updates to beapplied to a particular system (e.g., sub servers, nodes of subservers). A configuration object may include jobs (e.g., hierarchy ofjobs) converted from the configuration definition object. The jobs maybe applied by different systems to implement the patch/updates.

A configuration definition object may support generation of multipledifferent configuration objects. Different configuration objects (e.g.,particular system patches) may be generated based on the configurationdefinition object, relevant system characteristics, and/or otherinformation. For example, a single configuration definition object maybe used to automatically generate different system patches based on theparticular characteristics of different systems to which theconfiguration will be applied.

A configuration definition object may be used to apply differentimplementations of the same underlying configuration to multiplecomponents of the environment 100 (e.g., the central server 110, the subserver A 120, the sub server B 130, nodes of the central server 110/thesub servers 120, 130). For example, a configuration definition objectmay be used to apply different implementations of the same underlyingconfiguration to multiple servers/sub servers/nodes via patches/updatesthat takes into account individual system's characteristics. Thedifferent implementations may be applied to the different components ofthe environment 100 based on a hierarchy of configuration in theconfiguration definition object. The hierarchy of configuration mayinclude a level of files for individual stacks, a level of files forstack types, and a level of files for common files. Other levels and/orarrangement of levels are contemplated.

While the systems and methods are described herein with respect toapplying patches/updates to different components of the environment,this is merely as an example and is not limiting. The systems andmethods may be used to provide continuous configuration deployment forother purposes, such as for checking stack compliancy, data collection,remote control, authorization/authentication, and/or other continuousconfiguration deployment.

The configuration engine 114 may be configured to manage one or moreconfiguration definition objects, one or more configuration objects,and/or other files for continuous configuration deployment. In someembodiments, the configuration engine 114 may be implemented as a serverapplication (e.g., Java server application). The configuration engine114 may receive one or more configuration definition objects. Theconfiguration definition objects may be received from one or more users(e.g., entered by a user) and/or one or more systems (e.g., receivedfrom a remote computing system), and/or generated on the central server110. The configuration engine 114 may be configured to determine when aconfiguration definition object is committed to the datastore 112 and/orother locations. In some embodiments, the configuration definitionobject being committed to the datastore 112 may include theconfiguration definition object being committed to one or morerepositories (e.g., version control repository, Git repository) forstoring changes for one or more components of the environment 100. Insome embodiments, the configuration engine 114 may be configured tocommit the configuration definition object to the datastore 112. Forexample, the configuration engine 114 may continuously and/orperiodically integrate configuration definition objects into a versioncontrol repository/Git repository in the datastore 112.

The configuration engine 114 may be configured to generate one or moreconfiguration objects based on a configuration definition object,relevant system characteristics, and/or other information. Relevantsystem characteristics may include characteristics of a system to whichthe configuration will be applied. Characteristics of a system mayinclude information relating to software and/or hardware of the system.For example, characteristics of a system may include one or more ofversion information, context, operating environment, identifier (e.g.,stack identifier), type (e.g., stack type), and/or other characteristicsof the system. For example, based on a configuration to be applied tothe sub server A 120 (and/or nodes of the sub server A 120) and the subserver B 130 (and/or nodes of the sub server B 130), the configurationengine 114 may generate different configuration objects based on theconfiguration definition object and the characteristic(s) of the subserver A 120 (and/or the nodes of the sub server A 120) and the subserver B 130 (and/or the nodes of the sub server B 130), respectively.The configuration object for the sub server A 120 (and/or the nodes ofthe sub server A 120) may be different from the configuration object forthe sub server B 130 (and/or the nodes of the sub server B 130). Theconfiguration object for the sub server A 120 may include a uniquecombination of configuration(s) contained in the configurationdefinition object, which may be determined based on thecharacteristic(s) of the sub server A 120 (and/or the nodes of the subserver A 120). The configuration object for the sub server B 130 mayinclude a unique combination of configuration(s) contained in theconfiguration definition object, which may be determined based on thecharacteristic(s) of the sub server B 130 (and/or the nodes of the subserver B 130).

The configuration engine 114 may be configured to execute one or moreconfiguration objects based on a service request. For example, theconfiguration engine 114 may execute a configuration object for the subserver A 120 based on a service request. A service request may refer toa request by a system to apply a configuration (e.g., a system patchrequest associated with a scheduled maintenance) to the system oranother system. The service request may be entered at the central server110 and/or may be received from another system (e.g., the sub server A120). For example, the server request may be received based on executionof a maintenance operation (e.g., scheduled maintenance) at the subserver A 120). Executing the configuration object may apply theconfiguration in the configuration object to the relevant system (e.g.,sub server A 120). Executing the configuration object may includerunning the configuration object at the central server 110 to apply theconfiguration and/or providing the configuration object to the relevantsystem (e.g., sub server A 120) and having the relevant system run theconfiguration object to apply the configuration.

In some embodiments, a configuration may be applied to a system usingone or more definitions/tasks (e.g., API) and one or more programmingroutines (e.g., handlers) to carry out/perform the definitions/tasks.For example, a configuration object may include one or more APIs and oneor more handlers. The API(s) and the handler(s) may be executed on thesame machine or on different machines. Execution of a configurationobject may include execution of the API(s) and the handler(s) on thesame system or on different system. For example, a server applicationrunning on the sub server A 120 may run into an API, which requires ahandler not present on the sub server A 120. The server application mayrequest handler execution/forwarding from other systems (e.g., thecentral server 110, the sub server B 130).

The communication engine 116 may be configured to provide one or moreconfiguration definition objects to one or more remote systems (e.g.,the sub server A 120, the sub server B 130). The configurationdefinition object(s) may be provided over one or more communicationnetworks. A configuration definition object may be provided by thecommunication engine 116 to a remote system in response to adetermination that the configuration definition object has beencommitted to the datastore 112 and/or other locations. In someembodiments, the configuration definition object being committed to thedatastore 112 may include the configuration definition object beingcommitted to one or more repositories (e.g., version control repository,Git repository) for storing changes for one or more components of theenvironment 100. In some embodiments, the communication engine 116 maybe implemented as a server application (e.g., Java server application).

For example, in response to a new configuration definition object beingintegrated into a version control repository/Git repository, thecommunication engine 116 may provide the configuration definition objectto a remote system. This may automate the provision of a configurationdefinition object to a remote system based on the configurationdefinition object being committed to the version control repository/Gitrepository. This automation of configuration definition object provisionmay help ensure remote systems consistently obtain currentupdates/patches without a user (e.g., administrator) having to manuallyrequest and/or provide updates. This automation of configurationdefinition object provision may help ensure remote systems consistentlyobtain current updates/patches in advance of a scheduled maintenance,which may reduce the length of a maintenance operation (e.g., byreducing/eliminating the time needed to download the updates/patches).Reducing the length of the maintenance operation may enable systems toreduce the amount of time the systems are down/offline for maintenance.

The communication engine 116 may be configured to check whether a remotesystem is capable of receiving the configuration definition object. Forexample, a remote system may not be able to receive the configurationdefinition object because the remote system is down, there is no activenetwork connection between the central server 110 and the remote system,and/or the remote system is otherwise occupied. The communication engine116 may be configured to provide the configuration definition object tothe remote system (e.g., the sub server A 120) when the remote system iscapable of receiving the configuration definition object. Thecommunication engine 116 may be configured to provide the configurationdefinition object to another remote system (e.g., the sub server B 130),enabling the remote system (e.g. the sub server A 120) to obtain theconfiguration definition object from the other remote system rather thanthe central server 110.

The communication engine 116 may be configured to provide one or moreconfiguration definition objects to one or more remote systems inresponse to receiving one or more configuration requests from the remotesystem(s). A configuration request may indicate the configurationdefinition object (e.g., using identifier, system characteristics,hashing). The communication engine 116 may receive a configurationrequest from a remote system when the remote system has not previouslyreceived the configuration definition object from the central server 110or another remote system. For example, the communication engine 116 mayreceive a configuration request from the sub server B 130 based on thesub server B 130 requiring the configuration definition object for amaintenance operation. The sub server B 130 may not have received theconfiguration definition object from the central server 110 or anotherremote system (e.g., the sub server A 120).

In some embodiments, the communication engine 116 may be configured toprovide one or more configuration objects to one or more remote system(e.g., the sub server A 120, the sub server B 130). The configurationobject(s) may be provided to the remote system(s) as part of executionof the configuration object.

In various embodiments, the sub server A 120 may include a datastore A122, a configuration engine A 124, and a communication engine A 126. Insome embodiments, the datastore A 122 may be configured to implementsome, or all, of the functionalities of the datastore 112 as describedabove. In some embodiments, the configuration engine A 124 may beconfigured to implement some, or all, of the functionalities of theconfiguration engine 114 as described above. In some embodiments, thecommunication engine A 126 may be configured to implement some, or all,of the functionalities of the communication engine 116 as describedabove.

In some embodiments, the sub server A 120 may include/be connected toone or more nodes (e.g., clients). For example, the sub server A 120 mayinclude/be connected to a first node and a second node. The datastore A122 may include one or more configuration definition objects,configuration objects, and/or other files to be used by one or morecomponents of the environment 100. For example, the datastore A 122 mayinclude one or more configuration definition objects received from aremote datastore (e.g., the datastore 112, the datastore B 132). Thedatastore A 122 may provide a local cache for storing information (e.g.,configuration definition objects).

The configuration engine A 124 may be configured to manage one or moreconfiguration definition objects, one or more configuration objects,and/or other files for continuous configuration deployment. In someembodiments, the configuration engine A 124 may be implemented as aserver application (e.g., Java server application). The configurationengine A 124 may store one or more configuration definition objects froma remote datastore (e.g., the datastore 112, the datastore B 132).

The configuration engine A 124 may be configured to generate one or moreconfiguration objects based on a configuration definition object,relevant system characteristics, and/or other information. For example,based on a configuration to be applied to the sub server A 120, a firstnode of the sub server A 120, and a second node of the sub server A 120,the configuration engine A 124 may generate different configurationobjects based on the configuration definition object and thecharacteristic(s) of the sub server A 120, first node, and the secondnode, respectively. The configuration objects for the sub server A 120,the first node, and the second node may individually include a uniquecombination of configuration(s) contained in the configurationdefinition object, which may be determined based on thecharacteristic(s) of the sub server A 120, the first node, and thesecond node, respectively, and/or other information.

The configuration engine A 124 may be configured to execute one or moreconfiguration objects based on a service request. For example, theconfiguration engine A 124 may execute a configuration object for thesub server A 120, a first node of the sub server A 120, and/or a secondnode of the sub server A 120 based on a service request. The servicerequest may be entered at the sub server A 120 and/or may be receivedfrom another system (e.g., the first node, the second node). Forexample, the server request may be received based on execution of amaintenance operation (e.g., scheduled maintenance). Executing theconfiguration object may apply the configuration in the configurationobject to the sub server A 120, the first node, and/or the second node.Executing the configuration object may include running the configurationobject at the sub server A 120 to apply the configuration and/orproviding the configuration object to the first node and/or the secondnode and having the first node/second node run the configuration objectto apply the configuration. In some embodiments, one or more servicerequests may be received by the sub server A 120 subsequent to the subserver A 120 having obtained the necessary configuration definitionobject(s).

The configuration engine A 124 may include and/or receive allautomations required to manage itself and/or its nodes with respect toconfiguration deployment. For example, a configuration definition objectobtained from a remote datastore may include a collection of scripts tobe applied for a particular configuration. The configuration engine A124 may include and/or receive all automations required toconvert/compile the collection of scripts into a hierarchy of jobs andrun the jobs. Such provision/use of the configuration definition objectsmay allow a network of systems to be centrally defined (e.g., defined bythe central server 110) and de-centrally managed (e.g., managed by thesub server A 120).

In some embodiments, a configuration may be applied to a system usingone or more definitions/tasks (e.g., API) and one or more programmingroutines (e.g., handlers) to carry out/perform the definitions/tasks. AnAPI and a handler may be executed on the same machine or on differentmachines. For example, a server application running on a first node ofthe sub server A 120 may run into an API, which requires a handler notpresent on the first node. The server application may request handlerexecution/forwarding by other systems (e.g., the central server 110, thesub server A 120, the sub server B 130).

The communication engine A 126 may be configured to obtain one or moreconfiguration definition objects from one or more remote datastores(e.g., the datastore 112, the database B 132). The configurationdefinition object(s) may be obtained by the communication engine A 126from a remote database in response to a configuration definition objectbeing committed to the remote datastore and/or other locations. In someembodiments, the configuration definition object being committed to theremote datastore may include the configuration definition object beingcommitted to one or more repositories (e.g., version control repository,Git repository) for storing changes for one or more components of theenvironment 100. In some embodiments, the communication engine A 126 maybe implemented as a server application (e.g., Java server application).

For example, in response to a new configuration definition object beingintegrated into a version control repository/Git repository, thecommunication engine A 126 may obtain the configuration definitionobject from a remote database. This may automate the reception of aconfiguration definition object from the remote database based on theconfiguration definition object being committed to the version controlrepository/Git repository. This automation of configuration definitionobject reception may help ensure that the sub server A 120 consistentlyobtains current updates/patches without a user (e.g., administrator)having to manually request and/or provide updates. This automation ofconfiguration definition object reception may help ensure that the subserver A 120 consistently obtains current updates/patches in advance ofa scheduled maintenance, which may reduce the length of a maintenanceoperation (e.g., by reducing/eliminating the time needed to download theupdates/patches). Reducing the length of the maintenance operation mayenable systems to reduce the amount of time the systems are down/offlinefor maintenance.

The communication engine A 126 may be configured to provide one or moreconfiguration definition objects to one or more remote systems inresponse to receiving one or more configuration requests from the remotesystem(s). The communication engine A 126 may receive a configurationrequest from a remote system when the remote system has not previouslyreceived the configuration definition object from the central server 110or another remote system. For example, the communication engine A 126may receive a configuration request from the sub server B 130 based onthe sub server B 130 requiring the configuration definition object for amaintenance operation. The sub server B 130 may not have received theconfiguration definition object from the central server 110 or anotherremote system.

In some embodiments, the communication engine A 126 may be configured toforward one or more configuration requests. The configuration request(s)may be forwarded based on the sub server A 120 not having theconfiguration definition object indicated by the configuration request.The communication engine A 126 may forward the configuration request(s)to the central server 110 and/or another remote system (e.g., anothersub server). In some embodiments, the communication engine A 126 mayreceive the indicated configuration definition object from the centralserver 110 and/or another remote system. The indicated configurationdefinition object may be stored at the datastore A 122. In someembodiments, the indicated configuration definition object may be storedfor a set period of time (e.g., temporarily cached). In someembodiments, the indicated configuration definition object may beprovided by the central server 110 and/or another remote system(s) tothe system that originally sent the configuration request(s), and thecommunication engine A 126 may not receive the indicated configurationdefinition object. Forwarding/routing of configuration requests mayreduce the load on the central server 110 and/or may help ensure theremote systems (e.g., sub servers, nodes of sub server) to receiveupdates even under poor network conditions (e.g., the central server 110goes down, and/or the remote system loses network connectivity with thecentral server 110).

In some embodiments, the communication engine A 126 may be configured toprovide one or more configuration objects to one or more remote system(e.g., the sub server B 130, one or more nodes of the sub server A 120).The configuration object(s) may be provided to the remote system(s) aspart of execution of the configuration object.

In various embodiments, the sub server B 130 may include a datastore B132, a configuration engine B 134, and a communication engine B 136. Insome embodiments, the datastore B 132 may be configured to implementsome, or all, of the functionalities of the datastore A 122 as describedabove. In some embodiments, the configuration engine B 134 may beconfigured to implement some, or all, of the functionalities of theconfiguration engine A 124 as described above. In some embodiments, thecommunication engine B 136 may be configured to implement some, or all,of the functionalities of the communication engine A 126 as describedabove.

In some embodiments, the sub server B 130 may include/be connected toone or more nodes (e.g., clients). For example, the sub server B 130 mayinclude/be connected to a first node and a second node. The datastore B132 may include one or more configuration definition objects,configuration objects, and/or other files to be used by one or morecomponents of the environment 100. For example, the datastore B 132 mayinclude one or more configuration definition objects received from aremote datastore (e.g., the datastore 112, the datastore A 122). Thedatastore B 132 may provide a local cache for storing information (e.g.,configuration definition objects).

The configuration engine B 134 may be configured to manage one or moreconfiguration definition objects, one or more configuration objects,and/or other files for continuous configuration deployment. In someembodiments, the configuration engine B 134 may be implemented as aserver application (e.g., Java server application). The configurationengine B 134 may store one or more configuration definition objects froma remote datastore (e.g., the datastore 112, the datastore A 122).

The configuration engine B 134 may be configured to generate one or moreconfiguration objects based on a configuration definition object,relevant system characteristics, and/or other information. For example,based on a configuration to be applied to the sub server B 130, a firstnode of the sub server B 130, and a second node of the sub server B 130,the configuration engine B 134 may generate different configurationobjects based on the configuration definition object and thecharacteristic(s) of the sub server B 130, first node, and the secondnode, respectively.

The configuration engine B 134 may be configured to execute one or moreconfiguration objects based on a service request. For example, theconfiguration engine B 134 may execute a configuration object for thesub server B 130, a first node of the sub server B 130, and/or a secondnode of the sub server B 130 based on a service request. Executing theconfiguration object may apply the configuration in the configurationobject to the sub server B 130, the first node, and/or the second node.Executing the configuration object may include running the configurationobject at the sub server B 120 to apply the configuration and/orproviding the configuration object to the first node and/or the secondnode and having the first node/second node run the configuration objectto apply the configuration. The configuration engine B 134 may includeand/or receive all automations required to manage itself and/or itsnodes. These automations may allow a network of systems to be centrallydefined (e.g., defined by the central server 110) and de-centrallymanaged (e.g., managed by the sub server B 130). In some embodiments, aconfiguration may be applied to a system using one or moredefinitions/tasks (e.g., API) and one or more programming routines(e.g., handlers) to carry out/perform the definitions/tasks. Executionof the configuration object may include execution of the API(s) and thehandler(s) on the same system or on different system.

The communication engine B 136 may be configured to obtain one or moreconfiguration definition objects from one or more remote datastores(e.g., the datastore 112, the database A 122). The configurationdefinition object(s) may be obtained by the communication engine B 136from a remote database in response to a configuration definition objectbeing committed to the remote datastore/repositor(ies) and/or otherlocations. In some embodiments, the communication engine B 136 may beimplemented as a server application (e.g., Java server application).

The communication engine B 136 may be configured to provide one or moreconfiguration definition objects to one or more remote systems inresponse to receiving one or more configuration requests from the remotesystem(s). The communication engine B 136 may receive a configurationrequest from a remote system when the remote system has not previouslyreceived the configuration definition object from the central server 110or another remote system. For example, the communication engine B 136may receive a configuration request from the sub server A 120 based onthe sub server A 120 requiring the configuration definition object for amaintenance operation. In some embodiments, the communication engine B136 may be configured to forward one or more configuration requestsbased on the sub server B 130 not having the configuration definitionobject indicated by the configuration request.

In some embodiments, the communication engine B 136 may be configured toprovide one or more configuration objects to one or more remote system(e.g., the sub server A 120, one or more nodes of the sub server B 130).The configuration object(s) may be provided to the remote system(s) aspart of execution of the configuration object.

FIG. 2 illustrates an example environment 200 for providing continuousconfiguration deployment, in accordance with various embodiments. Theexample environment 200 may include a sub server A 220, a client A-1230, and a client A-2 240. The sub server A 220, the client A-1 230, andthe client A-2 240 may include one or more processors and memory. Theprocessor(s) may be configured to perform various operations byinterpreting machine-readable instructions stored in the memory. In someembodiments, the sub server A 220 may be configured to implement some,or all, of the functionalities of the sub server A 120 as describedabove.

Prior to the example environment 200 shown in FIG. 2, the sub server A220 may have received one or more configuration definition objects froma remote datastore (e.g., data store 112, datastore B 132) as describedabove with respect to the sub server A 120. The configuration definitionobject(s) may be stored in the datastore A 222. In some embodiments, thedatastore A 222 may be configured to implement some, or all, of thefunctionalities of the datastore A 122. In some embodiments, theconfiguration engine A 224 may be configured to implement some, or all,of the functionalities of the configuration engine A 124 as describedabove. In some embodiments, the communication engine A 226 may beconfigured to implement some, or all, of the functionalities of thecommunication engine A 126 as described above.

The configuration engine A 224 may be configured to manage one or moreconfiguration definition objects, one or more configuration objects,and/or other files for continuous configuration deployment. In someembodiments, the configuration engine A 224 may be implemented as aserver application (e.g., Java server application).

The configuration engine A 224 may be configured to generate one or moreconfiguration objects based on a configuration definition object,relevant system characteristics, and/or other information. For example,based on a configuration to be applied to the sub server A 220, theclient A-1 230, and the client A-2 240, the configuration engine A 224may generate different configuration objects based on the configurationdefinition object and the characteristic(s) of the sub server A 220, theclient A-1 230, and the client A-2 240, respectively.

The configuration engine A 224 may be configured to execute one or moreconfiguration objects based on a service request. For example, theconfiguration engine A 224 may execute a configuration object for thesub server A 220, the client A-1 230, and/or the client A-2 240 based ona service request. Executing the configuration object may apply theconfiguration in the configuration object to the sub server A 220, theclient A-1 230, and/or the client A-2 240. Executing the configurationobject may include running the configuration object at the sub server A220 to apply the configuration and/or providing the configuration objectto the client A-1 230 and/or the client A-2 240 and having the clients230, 240 run the configuration object to apply the configuration.Obtaining the configuration definition object for the sub server A 220,the client A-1 230, and/or the client A-2 240 in advance of theconfiguration object execution may allow the sub server A 220 to applyconfiguration to the sub server A 220, the client A-1 230, and/or theclient A-2 240 without having connection to and/or without downloadingthe configuration definition object from a server (e.g., the centralserver 110, the sub server B 130).

The communication engine A 226 may be configured to provide one or moreconfiguration definition objects to one or more remote systems inresponse to receiving one or more configuration requests from the remotesystem(s). In some embodiments, the communication engine A 226 may beconfigured to forward one or more configuration requests (e.g., toanother remote system). In some embodiments, the communication engine A226 may be configured to provide one or more configuration objects toone or more remote system (e.g., the client A-1 230, the client A-2240). The configuration object(s) may be provided to the remotesystem(s) as part of execution of the configuration object.

FIG. 3 illustrates an example environment 300 for providing continuousconfiguration deployment, in accordance with various embodiments. Theexample environment 300 may include a central server 302, a sub server A312, a sub server B 314, a sub server C 316, a sub server D 318, aclient A 322, a client B 324, a client C 326, a client D 328, and aclient E 330. The central server 302, the sub servers 312, 314, 316,318, and the clients 322, 324, 326, 328, 330 may include one or moreprocessors and memory. The processor(s) may be configured to performvarious operations by interpreting machine-readable instructions storedin the memory.

In some embodiments, the central server 302 may be configured toimplement some, or all, of the functionalities of the central server 110as described above. In some embodiments, the sub servers 312, 314, 316,318 may be configured to implement some, or all, of the functionalitiesof the sub servers 120, 130, 220 as described above. In someembodiments, the clients 322, 324, 326, 328, 330 may be configured toimplement some, or all, of the functionalities of the clients 230, 240as described above. The central server 302 and/or one or more of the subservers 312, 314, 316, 318 may provide data/processing for operation ofone or more of the clients 322, 324, 326, 328, 330. The network ofconnections among the central server 302, the sub servers 312, 314, 316,318, and the clients 322, 324, 326, 328, 330 may form a mesh.

Configuration deployment on one or more of the sub servers 312, 314,316, 318, and the clients 322, 324, 326, 328, 330 may require one ormore configuration definition objects. The configuration definitionobjects may be centrally stored/generated at the central server 302.Having too many of the sub servers 312, 314, 316, 318, and/or theclients 322, 324, 326, 328, 330 attempting to contact the central server302 at/near the same time for the relevant configuration definitionobject may overwhelm the central server 302 and/or may lead toconflicts/loss of messages between the systems. Rather than waitinguntil for requests of the configuration definition object(s) by the subservers 312, 314, 316, 318, and/or the clients 322, 324, 326, 328, 330,the central server 302 may provide (e.g., push) the configurationdefinition objects to one or more of the sub servers 312, 314, 316, 318(e.g., when the configuration definition object is committed to adatastore/repository). The sub servers 312, 314, 316, 318 may cache theconfiguration definition object in a local datastore for use when theconfiguration is applied (e.g., during a scheduled maintenance).

When an operation is performed to apply a particular configuration to asystem, a check may be performed to see if it has the necessaryconfiguration definition object/configuration object. For example, whenan operation is performed to apply a particular configuration to theclient 330, a check may be performed to see if the sub server 318 hasthe necessary configuration object and/or the necessary configurationdefinition object to generate the configuration object. If the necessaryfile(s) are not located at the sub server 318, the request for thefile(s) may be forwarded to other systems in the environment 300. Forexample, the request for the file(s) may be forwarded to the sub servers314, 316. If the sub servers 314, 316 do not have the necessary file(s),they may forward the request to other systems (e.g., the central server302, the sub server 312). The system with the necessary file(s) mayrespond to the request by sending the file(s) to the sub server 318. Theroute taken by the file(s) may include the most direct route (e.g.,fastest path, path with least number of nodes) or may include the pathtaken by the request (e.g., retracing the path taken by the request). Insome implementations, one or more intermediate sub servers (sub serversbetween the system with the necessary file(s) and the sub server 318)may cache the file(s) locally (for a period of time). Caching thefile(s) may allow the intermediate sub servers to respond to futurerequest for the file(s) from another system. For example, subsequent tocaching the file(s) in its local datastore, the sub server 314 mayreceive a request for the same file(s) from the client 326. Because ithas cached the file(s), the sub server 314 may respond to the requestfrom the client 326.

Routing/forwarding of requests for file(s) may enable the environment300 to avoid overwhelming the central server 302 with the same requestand provide for scalability in providing continuous configurationdeployment. For example, the sub server 312 may include/be connected tothe clients 322, 324. The sub server 312 may request and receive fromthe central server 302 a particular configuration definition objectneeded to apply a particular configuration to the client 322. The subserver 312 may cache the particular configuration definition object inits local datastore, allowing the sub server 312 to use the cachedconfiguration definition object to apply the particular configuration tonot just the client 322, but also the client 324 during its maintenancewindow.

Routing/forwarding of requests for file(s) may enable the environment300 to operate when the central server 302 and/or some of the subservers 312, 314, 316, 318 are down, or when one or more connectionsbetween the systems are down. Routing and caching of configurationdefinition objects among different systems of the environment 300 mayprevent one of the systems (e.g., the central server 302) and/or certainconnections from becoming a critical infrastructure. For example, evenif the central server 302 is down/a connection to the central server 302is down, a sub server (e.g., the sub server 316) may be able to locatedthe necessary configuration definition object from another sub server(e.g., the sub server 312) that has cached the configuration definitionobject.

The example method 500 maybe implemented in various computing systems or devices including one ormore processors.

At block 502, a central server may determine that a configurationdefinition object is committed to a datastore. At block 504, the centralserver may provide (e.g., push) the configuration definition object to asub server in response to the determination. At block 506, the subserver may receive and cache the configuration definition object in alocal datastore. At block 508, the sub server may generate aconfiguration object based on the configuration definition object. Atblock 510, the sub server may receive a service request. At block 512,the sub server may execute the configuration object in response to theservice request. At block 514, the sub server may receive aconfiguration request for the configuration definition object from aremote system. At block 516, the sub server may provide (e.g., forward)the configuration definition object to the remote system in response tothe configuration request.

Hardware Implementation

The techniques described herein are implemented by one or morespecial-purpose computing devices. The special-purpose computing devicesmay be hard-wired to perform the techniques, or may include circuitry ordigital electronic devices such as one or more application-specificintegrated circuits (ASICs) or field programmable gate arrays (FPGAs)that are persistently programmed to perform the techniques, or mayinclude one or more hardware processors programmed to perform thetechniques pursuant to program instructions in firmware, memory, otherstorage, or a combination. Such special-purpose computing devices mayalso combine custom hard-wired logic, ASICs, or FPGAs with customprogramming to accomplish the techniques. The special-purpose computingdevices may be desktop computer systems, server computer systems,portable computer systems, handheld devices, networking devices or anyother device or combination of devices that incorporate hard-wiredand/or program logic to implement the techniques.

Computing device(s) are generally controlled and coordinated byoperating system software, such as iOS, Android, Chrome OS, Windows XP,Windows Vista, Windows 7, Windows 8, Windows Server, Windows CE, Unix,Linux, SunOS, Solaris, iOS, Blackberry OS, VxWorks, or other compatibleoperating systems. In other embodiments, the computing device may becontrolled by a proprietary operating system. Conventional operatingsystems control and schedule computer processes for execution, performmemory management, provide file system, networking, I/O services, andprovide a user interface functionality, such as a graphical userinterface (“GUI”), among other things.

FIG. 6 is a block diagram that illustrates a computer system 600 uponwhich any of the embodiments described herein may be implemented. Thecomputer system 600 includes a bus 602 or other communication mechanismfor communicating information, one or more hardware processors 604coupled with bus 602 for processing information. Hardware processor(s)604 may be, for example, one or more general purpose microprocessors.

The computer system 600 also includes a main memory 606, such as arandom access memory (RAM), cache and/or other dynamic storage devices,coupled to bus 602 for storing information and instructions to beexecuted by processor 604. Main memory 606 also may be used for storingtemporary variables or other intermediate information during executionof instructions to be executed by processor 604. Such instructions, whenstored in storage media accessible to processor 604, render computersystem 600 into a special-purpose machine that is customized to performthe operations specified in the instructions.

The computer system 600 further includes a read only memory (ROM) 608 orother static storage device coupled to bus 602 for storing staticinformation and instructions for processor 604. A storage device 610,such as a magnetic disk, optical disk, or USB thumb drive (Flash drive),etc., is provided and coupled to bus 602 for storing information andinstructions.

The computer system 600 may be coupled via bus 602 to a display 612,such as a cathode ray tube (CRT) or LCD display (or touch screen), fordisplaying information to a computer user. An input device 614,including alphanumeric and other keys, is coupled to bus 602 forcommunicating information and command selections to processor 604.Another type of user input device is cursor control 616, such as amouse, a trackball, or cursor direction keys for communicating directioninformation and command selections to processor 604 and for controllingcursor movement on display 612. This input device typically has twodegrees of freedom in two axes, a first axis (e.g., x) and a second axis(e.g., y), that allows the device to specify positions in a plane. Insome embodiments, the same direction information and command selectionsas cursor control may be implemented via receiving touches on a touchscreen without a cursor.

The computing system 600 may include a user interface module toimplement a GUI that may be stored in a mass storage device asexecutable software codes that are executed by the computing device(s).This and other modules may include, by way of example, components, suchas software components, object-oriented software components, classcomponents and task components, processes, functions, attributes,procedures, subroutines, segments of program code, drivers, firmware,microcode, circuitry, data, databases, data structures, tables, arrays,and variables.

In general, the word “module,” as used herein, refers to logic embodiedin hardware or firmware, or to a collection of software instructions,possibly having entry and exit points, written in a programminglanguage, such as, for example, Java, C or C++. A software module may becompiled and linked into an executable program, installed in a dynamiclink library, or may be written in an interpreted programming languagesuch as, for example, BASIC, Perl, or Python. It will be appreciatedthat software modules may be callable from other modules or fromthemselves, and/or may be invoked in response to detected events orinterrupts. Software modules configured for execution on computingdevices may be provided on a computer readable medium, such as a compactdisc, digital video disc, flash drive, magnetic disc, or any othertangible medium, or as a digital download (and may be originally storedin a compressed or installable format that requires installation,decompression or decryption prior to execution). Such software code maybe stored, partially or fully, on a memory device of the executingcomputing device, for execution by the computing device. Softwareinstructions may be embedded in firmware, such as an EPROM. It will befurther appreciated that hardware modules may be comprised of connectedlogic units, such as gates and flip-flops, and/or may be comprised ofprogrammable units, such as programmable gate arrays or processors. Themodules or computing device functionality described herein arepreferably implemented as software modules, but may be represented inhardware or firmware. Generally, the modules described herein refer tological modules that may be combined with other modules or divided intosub-modules despite their physical organization or storage.

The computer system 600 may implement the techniques described hereinusing customized hard-wired logic, one or more ASICs or FPGAs, firmwareand/or program logic which in combination with the computer systemcauses or programs computer system 600 to be a special-purpose machine.According to one embodiment, the techniques herein are performed bycomputer system 600 in response to processor(s) 604 executing one ormore sequences of one or more instructions contained in main memory 606.Such instructions may be read into main memory 606 from another storagemedium, such as storage device 610. Execution of the sequences ofinstructions contained in main memory 606 causes processor(s) 604 toperform the process steps described herein. In alternative embodiments,hard-wired circuitry may be used in place of or in combination withsoftware instructions.

The term “non-transitory media,” and similar terms, as used hereinrefers to any media that store data and/or instructions that cause amachine to operate in a specific fashion. Such non-transitory media maycomprise non-volatile media and/or volatile media. Non-volatile mediaincludes, for example, optical or magnetic disks, such as storage device610. Volatile media includes dynamic memory, such as main memory 606.Common forms of non-transitory media include, for example, a floppydisk, a flexible disk, hard disk, solid state drive, magnetic tape, orany other magnetic data storage medium, a CD-ROM, any other optical datastorage medium, any physical medium with patterns of holes, a RAM, aPROM, and EPROM, a FLASH-EPROM, NVRAM, any other memory chip orcartridge, and networked versions of the same.

Non-transitory media is distinct from but may be used in conjunctionwith transmission media. Transmission media participates in transferringinformation between non-transitory media. For example, transmissionmedia includes coaxial cables, copper wire and fiber optics, includingthe wires that comprise bus 602. Transmission media can also take theform of acoustic or light waves, such as those generated duringradio-wave and infra-red data communications.

Various forms of media may be involved in carrying one or more sequencesof one or more instructions to processor 604 for execution. For example,the instructions may initially be carried on a magnetic disk or solidstate drive of a remote computer. The remote computer can load theinstructions into its dynamic memory and send the instructions over atelephone line using a modem. A modem local to computer system 600 canreceive the data on the telephone line and use an infra-red transmitterto convert the data to an infra-red signal. An infra-red detector canreceive the data carried in the infra-red signal and appropriatecircuitry can place the data on bus 602. Bus 602 carries the data tomain memory 606, from which processor 604 retrieves and executes theinstructions. The instructions received by main memory 606 may retrievesand executes the instructions. The instructions received by main memory606 may optionally be stored on storage device 610 either before orafter execution by processor 604.

The computer system 600 also includes a communication interface 618coupled to bus 602. Communication interface 618 provides a two-way datacommunication coupling to one or more network links that are connectedto one or more local networks. For example, communication interface 618may be an integrated services digital network (ISDN) card, cable modem,satellite modem, or a modem to provide a data communication connectionto a corresponding type of telephone line. As another example,communication interface 618 may be a local area network (LAN) card toprovide a data communication connection to a compatible LAN (or WANcomponent to communicated with a WAN). Wireless links may also beimplemented. In any such implementation, communication interface 618sends and receives electrical, electromagnetic or optical signals thatcarry digital data streams representing various types of information.

A network link typically provides data communication through one or morenetworks to other data devices. For example, a network link may providea connection through local network to a host computer or to dataequipment operated by an Internet Service Provider (ISP). The ISP inturn provides data communication services through the world wide packetdata communication network now commonly referred to as the “Internet”.Local network and Internet both use electrical, electromagnetic oroptical signals that carry digital data streams. The signals through thevarious networks and the signals on network link and throughcommunication interface 618, which carry the digital data to and fromcomputer system 600, are example forms of transmission media.

The computer system 600 can send messages and receive data, includingprogram code, through the network(s), network link and communicationinterface 618. In the Internet example, a server might transmit arequested code for an application program through the Internet, the ISP,the local network and the communication interface 618.

The received code may be executed by processor 604 as it is received,and/or stored in storage device 610, or other non-volatile storage forlater execution.

Each of the processes, methods, and algorithms described in thepreceding sections may be embodied in, and fully or partially automatedby, code modules executed by one or more computer systems or computerprocessors comprising computer hardware. The processes and algorithmsmay be implemented partially or wholly in application-specificcircuitry.

The various features and processes described above may be usedindependently of one another, or may be combined in various ways. Allpossible combinations and sub-combinations are intended to fall withinthe scope of this disclosure. In addition, certain method or processblocks may be omitted in some embodiments. The methods and processesdescribed herein are also not limited to any particular sequence, andthe blocks or states relating thereto can be performed in othersequences that are appropriate. For example, described blocks or statesmay be performed in an order other than that specifically disclosed, ormultiple blocks or states may be combined in a single block or state.The example blocks or states may be performed in serial, in parallel, orin some other manner. Blocks or states may be added to or removed fromthe disclosed example embodiments. The example systems and componentsdescribed herein may be configured differently than described. Forexample, elements may be added to, removed from, or rearranged comparedto the disclosed example embodiments.

Conditional language, such as, among others, “can,” “could,” “might,” or“may,” unless specifically stated otherwise, or otherwise understoodwithin the context as used, is generally intended to convey that certainembodiments include, while other embodiments do not include, certainfeatures, elements and/or steps. Thus, such conditional language is notgenerally intended to imply that features, elements and/or steps are inany way required for one or more embodiments or that one or moreembodiments necessarily include logic for deciding, with or without userinput or prompting, whether these features, elements and/or steps areincluded or are to be performed in any particular embodiment.

Any process descriptions, elements, or blocks in the flow diagramsdescribed herein and/or depicted in the attached figures should beunderstood as potentially representing modules, segments, or portions ofcode which include one or more executable instructions for implementingspecific logical functions or steps in the process. Alternateimplementations are included within the scope of the embodimentsdescribed herein in which elements or functions may be deleted, executedout of order from that shown or discussed, including substantiallyconcurrently or in reverse order, depending on the functionalityinvolved, as would be understood by those skilled in the art.

It should be emphasized that many variations and modifications may bemade to the above-described embodiments, the elements of which are to beunderstood as being among other acceptable examples. All suchmodifications and variations are intended to be included herein withinthe scope of this disclosure. The foregoing description details certainembodiments of the invention. It will be appreciated, however, that nomatter how detailed the foregoing appears in text, the invention can bepracticed in many ways. As is also stated above, it should be noted thatthe use of particular terminology when describing certain features oraspects of the invention should not be taken to imply that theterminology is being re-defined herein to be restricted to including anyspecific characteristics of the features or aspects of the inventionwith which that terminology is associated. The scope of the inventionshould therefore be construed in accordance with the appended claims andany equivalents thereof.

Engines, Components, and Logic

Certain embodiments are described herein as including logic or a numberof components, engines, or mechanisms. Engines may constitute eithersoftware engines (e.g., code embodied on a machine-readable medium) orhardware engines. A “hardware engine” is a tangible unit capable ofperforming certain operations and may be configured or arranged in acertain physical manner. In various example embodiments, one or morecomputer systems (e.g., a standalone computer system, a client computersystem, or a server computer system) or one or more hardware engines ofa computer system (e.g., a processor or a group of processors) may beconfigured by software (e.g., an application or application portion) asa hardware engine that operates to perform certain operations asdescribed herein.

In some embodiments, a hardware engine may be implemented mechanically,electronically, or any suitable combination thereof. For example, ahardware engine may include dedicated circuitry or logic that ispermanently configured to perform certain operations. For example, ahardware engine may be a special-purpose processor, such as aField-Programmable Gate Array (FPGA) or an Application SpecificIntegrated Circuit (ASIC). A hardware engine may also includeprogrammable logic or circuitry that is temporarily configured bysoftware to perform certain operations. For example, a hardware enginemay include software executed by a general-purpose processor or otherprogrammable processor. Once configured by such software, hardwareengines become specific machines (or specific components of a machine)uniquely tailored to perform the configured functions and are no longergeneral-purpose processors. It will be appreciated that the decision toimplement a hardware engine mechanically, in dedicated and permanentlyconfigured circuitry, or in temporarily configured circuitry (e.g.,configured by software) may be driven by cost and time considerations.

Accordingly, the phrase “hardware engine” should be understood toencompass a tangible entity, be that an entity that is physicallyconstructed, permanently configured (e.g., hardwired), or temporarilyconfigured (e.g., programmed) to operate in a certain manner or toperform certain operations described herein. As used herein,“hardware-implemented engine” refers to a hardware engine. Consideringembodiments in which hardware engines are temporarily configured (e.g.,programmed), each of the hardware engines need not be configured orinstantiated at any one instance in time. For example, where a hardwareengine comprises a general-purpose processor configured by software tobecome a special-purpose processor, the general-purpose processor may beconfigured as respectively different special-purpose processors (e.g.,comprising different hardware engines) at different times. Softwareaccordingly configures a particular processor or processors, forexample, to constitute a particular hardware engine at one instance oftime and to constitute a different hardware engine at a differentinstance of time.

Hardware engines can provide information to, and receive informationfrom, other hardware engines. Accordingly, the described hardwareengines may be regarded as being communicatively coupled. Where multiplehardware engines exist contemporaneously, communications may be achievedthrough signal transmission (e.g., over appropriate circuits and buses)between or among two or more of the hardware engines. In embodiments inwhich multiple hardware engines are configured or instantiated atdifferent times, communications between such hardware engines may beachieved, for example, through the storage and retrieval of informationin memory structures to which the multiple hardware engines have access.For example, one hardware engine may perform an operation and store theoutput of that operation in a memory device to which it iscommunicatively coupled. A further hardware engine may then, at a latertime, access the memory device to retrieve and process the storedoutput. Hardware engines may also initiate communications with input oroutput devices, and can operate on a resource (e.g., a collection ofinformation).

The various operations of example methods described herein may beperformed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implemented enginesthat operate to perform one or more operations or functions describedherein. As used herein, “processor-implemented engine” refers to ahardware engine implemented using one or more processors.

Similarly, the methods described herein may be at least partiallyprocessor-implemented, with a particular processor or processors beingan example of hardware. For example, at least some of the operations ofa method may be performed by one or more processors orprocessor-implemented engines. Moreover, the one or more processors mayalso operate to support performance of the relevant operations in a“cloud computing” environment or as a “software as a service” (SaaS).For example, at least some of the operations may be performed by a groupof computers (as examples of machines including processors), with theseoperations being accessible via a network (e.g., the Internet) and viaone or more appropriate interfaces (e.g., an Application ProgramInterface (API)).

The performance of certain of the operations may be distributed amongthe processors, not only residing within a single machine, but deployedacross a number of machines. In some example embodiments, the processorsor processor-implemented engines may be located in a single geographiclocation (e.g., within a home environment, an office environment, or aserver farm). In other example embodiments, the processors orprocessor-implemented engines may be distributed across a number ofgeographic locations.
